LS Swap Starter won't spin Weird issue I am having with my LS Swap'd E30. Finally got to the point to try to start it and ran into an issue. The starter will not spin the bendix will initiate into the flywheel but will not spin and then when I let off the key it clicks back. Now I have tested the battery it is good. I tried a new starter still the same thing. I added extra grounds still does the same thing. Last ditch effort I jumped the battery and it still did the same thing. So I wanted to get your opinion of things to try. At this point I think it is one of two things either the starter isn't aligned correctly and needs shims or the bmw ignition is not sending enough amps to the starter. But I was told that LS starters don't typically need shims. I added a video below any insight you have would be appreciated.

That's why you only get a click. The 12V from the ignition switch goes to the small terminal to engage the solenoid.
The starter motor should have a large gauge wire direct to the large terminal on the starter.

Here is a thread that may help https://ls1tech.com/forums/conversio...er-wiring.html
There are two wires required for the starter to function, the one from your harness and the main power cable to the battery.

Ok got the starter working and the car fires up but won't stay running I have VATS turned off and the fuel pump is on and stays running after cranking it so I'm back lost. I have tried with the maf plugged in and with it not. The tune is for a ls1 map and I am using a truck map could that be the cause?
